Rudder torque

[jjackkrash]

I'd like to add a little rudder torque to the Am. Skier--its pretty neutral right now. Which side do you grind on for a non-nautique (port or starboard side)? I have heard conflicting reports so I'd like to hear from someone who is 100% sure. Any other tips before I start grinding?

 

Thanks,

 

Jack

Grind the right rear if you want it to pull right. You just round off the right rear trailing edge a bit like an airfoil. Do a small amount at a time and then check it. You can ruin the rudder if you don't know what you are doing.

 

Here is a MC thread. http://www.mastercraft.com/teamtalk/archive/index.php/t-3599.html

 

Mastercraft has a diagram and directions.

Also, you should start feeling the rudder torque at about 26 mph and faster.

Thanks for the tips. I may break out the file today if I can work up the nerve.

You will need a grinder. That NIBRAL is tougher than it looks.

I used an angle grinder with the guard removed and a flap disc ( http://www.google.com/products/catalog?q=4+1/2+flap+disc&oe=utf-8&rls=org.mozilla:en-US:official&client=firefox-a&um=1&ie=UTF-8&cid=11548557516613645059&sa=X&ei=PZbBTdCuLNLYiALh-bmOAw&ved=0CGQQ8wIwAg# )

Hmm, I can do that, but I will need to bring the aircompressor and generator to the lake.

You can use a standard disc on the grinder, just go lightly and with a smooth even motion. Took a few swipes to get what I wanted.

Aw come-on!! I was hoping to find out how the file thing went :).

I have a bad-boy makita grinder with a 10" flat stone that I touch up rudders with. Have not had to do it in a while.

I drove the boat Yesterday and had my grinder handy but I had some kinks with Stargazer and my electrical system and I didn't get to the grinder. But I noted that the rudder is dead neutral and the boat floats a bit in the course so it needs to happen. I'll probably take a pass at it this weekend. The boat also lists a bit to port when under power with even weight and I am wondering if a little rudder torque will help with the list. We shall see soon, I suppose.

Update: I took a little swipe off the rudder with a grinder and it had little effect. I am going to get a little more aggressive and try again.
